CABLE-HAULED CAR.

Specification of Letters Patent.

Application filed May 13, 1912.

Serial No. 696,979.

To all whom it may concern:

Be it known that I, PAUL Bns'rA, a subject of the King ofPrussia,residing at Ratingcn, in the Kingdom of Prussia, Germany, haveinvented certain new and useful Improve ments in Cable-I-Iauled Cars, ofwhich the following is a specification.

This invention relates to a braking device for cars hauled by cables orby chains. The braking device operates automatically as soon as the caris released from the cable or chain.

According to this invention the braking device consists of brake-blockswhich are antomatically placed upon the rails in front of the wheels bythe releasing device as soon as the car is released from the cable orchain. The wheels run up the brake blocks whereby the car is immediatelystopped. The lower surfaces of the brake blocks which are pressed by thewheels upon the rails are roughened whereby a better braking action isinsured.

In the accompanying drawings the invention is shown by way of exampleFigure 1 shows in front elevation a tipping car having the improvedbraking de' vice; the brake-blocks are shown in lifted position. Fig. 2is a side elevation of Fig. 1. Fig. 3 is a side elevation, the brakeblocks being shown in the braking position. Fig. 4 is a detail viewshowing the roughened surface of the brake-blocks.

The continuous cable or chain Z is placed in a gripper fork a carried bythe car. This gripper fork a is loosely mounted in a hearing 6 fixedupon the front wall of the car. A rope or chain c is fixed to the shaftof the gripper fork a so that it winds around said shaft when thegripper fork is being turned. This chain has two branches (Z and e ofwhich the one (Z is guided in guide pieces f, the other one being guidedover grooved disks 9 and through guide pieces h. The brake blocks 2' arefixed at the ends of the branches (Z and e of the rope or chain. The

brake blocks are mounted upon angular cross rails and present extensions70 designed to grip over the heads of the rails (Figs'l and 3) wherebythey are securely brought into the proper position between the rails andthe wheels when they are released (Fig. 3).

Before the cable Z is placed into the gripper fork a this fork is turnedso that the chain 6 is wound around its shaft whereby the brake blocks2' are lifted off the rails m. If the car for any reason whatsoever isdisconnected from the cable Z the fork a, which is thus released, turnsback under the tension of the ropes or chains (cde) so that the chain cunwinds from the shaft of the fork and the brake-blocks which are thusreleased drop upon the rails immediately in front of the wheels. The carruns upon the blocks 70 whereby it is stopped. The lower surfaces of thebrakeblocks are roughened whereby a better adherence upon the rails isinsured. Theweightof the chains (0de) which connect the brake-blockswith the gripper fork could be increased by the addition of weights.

If the car has to move only along one incline, the brake-blocks need bearranged only at one side of the wheels but the releasing device remainsthe same as her'einbefore clescribed.

If the car is moved by hand the brake fork is looked after the chain chas been wound around the shaft of the fork and the brake-blocks 7c havebeen lifted off the rails; V

for this purpose a cotter n is inserted in alining openings in thegripper fork and its bearing (Fig. 1).

1. An automatic braking device for cable hauled ears comprising incombination brake-blocks, suspended in front of the wheels, chains towhich said brake-blocks are attached, a bearing fixed on the front wallof the car, a gripper fork loosely mounted in said bearing, and thechain of the brake blocks fixed to said fork so that it can be woundaround the fork shaft to lift the brake blocks off the rails,substantially as described and shown and for the purpose set forth.
